Description

Technical Field

[0001] This invention relates to the field of power battery component processing, specifically to a PACK battery pack module busbar forming processing equipment. Background Technology

[0002] A battery pack module refers to a battery assembly that combines multiple individual battery cells into a single unit. The main function of a battery module is to connect multiple cells in parallel or series to increase the voltage and energy storage capacity of the battery system. Currently, in most power distribution scenarios, the use of battery pack modules in conjunction with busbars can improve the reliability and stability of the power distribution system.

[0003] Currently, battery pack modules are widely used in energy storage systems for electric vehicles and hybrid vehicles, where busbars play a crucial role. Therefore, the molding and processing of busbars in battery pack modules is of paramount importance. This invention primarily focuses on the molding and processing of busbars that mate with the battery electrodes, such as... Figure 11 As shown, its internal structure mainly consists of stamping holes and gaskets. The gaskets are bent and have a circular bottom. The top of the gaskets is connected to the edge of the busbar stamping holes. When the stamped gaskets are placed horizontally, they are located on the underside of the main structure, which facilitates better contact and communication with the battery cells, making the current output more stable.

[0004] The forming process of busbars mainly involves two steps: stamping and bending. First, the raw material is positioned, and stamping is performed at the designated locations. Then, the internal structure is bent. The following problems exist in the forming process of PACK battery pack module busbars: 1. Traditionally, different processing equipment is used to perform stamping and bending of the busbars sequentially during the manufacturing process. However, in mass production, this process is time-consuming and inefficient, and cannot achieve integrated stamping and bending. 2. Currently, bending of the internal gaskets of PACK battery pack module busbars mostly uses specialized equipment for secondary bending. Since bending requires secondary positioning, inaccuracies in bending are possible. Furthermore, using specialized equipment is costly and cannot meet the demands of mass production.

[0015] Preferably, the fixing unit includes a placement frame installed in the middle of the upper end face of the movable frame, and multiple sets of through holes are located in the middle of the placement frame.

[0016] The beneficial effects of this invention are as follows: 1. This invention uses multi-stage push rods to quickly move the moving frame to the stamping unit and bending unit for forming processing, and uses a hydraulic cylinder to drive the busbar for stamping and bending, making the forming process of the internal gasket structure of the busbar more refined. At the same time, after stamping, it can quickly position and bend the internal gasket structure of the busbar that needs to be bent, realizing the integration of stamping and bending processing, which is conducive to improving the production efficiency of busbar processing and forming.

[0017] 2. This invention uses gears and racks to drive the follower plate and the push plate to move in opposite directions, so that the upper and lower surfaces of the corresponding fixed post and locking post are tightly fitted together. This clamps and fixes the gasket inside the busbar, and moves it to the right under the impact of the follower rod and the moving rack. This achieves structural shaping of the gasket structure inside the busbar that contacts and communicates with the battery cell, so that the gasket is located in the middle of the stamping hole and on the lower side of its main structure. This facilitates the installation of the busbar and the battery pack and makes the contact between the busbar and the battery smooth, resulting in a more stable current output.

[0018] 3. This invention uses a locking assembly to lock the position of the telescopic end of the locking post. Through the cooperation of the support rod, the rotating rod and the locking spring, the rotating rod can lock the position of the telescopic end of the locking post when the fixed post and the locking post are in close contact and the inside of the busbar is bent. This prevents the telescopic end of the locking post from moving upward and pushing the bent structure upward when it elastically expands and contracts, thereby ensuring the stability of the internal gasket structure of the busbar during bending.

[0032] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where no specific technology or conditions are specified in the embodiments, they shall be performed in accordance with the technology or conditions described in the literature in the field or in accordance with the product manual.

[0033] See Figure 1 A PACK battery pack module busbar forming processing equipment includes a base plate 1. A stamping unit 8 and a bending unit 9 are installed on the top of the base plate 1, with the bending unit 9 located behind the stamping unit 8. A fixing plate 2 and a vertical plate 3 are installed on the top of the base plate 1, with the fixing plate 2 located in front of the stamping unit 8 and the vertical plate 3 located behind the bending unit 9. A moving groove 4 is opened in the middle of the upper surface of the base plate 1, and the moving groove 4 is located between the fixing plate 2 and the vertical plate 3. A multi-stage push rod 5 is installed on the rear end face of the fixing plate 2. A moving frame 6 is installed on the telescopic end of the multi-stage push rod 5. The moving frame 6 is slidably connected inside the moving groove 4. A multiple set of through holes 61 are evenly opened in the middle of the upper end face of the moving frame 6. A fixing unit 7 is installed on the top of the moving frame 6.

[0034] This invention is used for the forming and processing of busbars in PACK battery pack modules. After stamping the busbars, this invention can quickly move them to the bending unit 9 and bend the internal gasket structure of the busbars. The busbar raw material is fixed above the moving frame 6 by the fixing unit 7. The multi-stage push rod 5 pushes the moving frame 6 to move within the moving groove 4 to transport the busbar raw material to the stamping unit 8 and the bending unit 9 for forming and processing. This achieves integrated stamping and bending processing of the busbars, saving processing costs and improving processing efficiency.

[0035] See Figure 1 The fixing unit 7 includes a placement frame 71 installed in the middle of the upper end face of the movable frame 6, and multiple sets of through holes 61 are located in the middle of the placement frame 71.

[0036] See Figure 2 and Figure 8 The stamping unit 8 includes a gantry crane 81 installed above the base plate 1 and located on both sides of the moving groove 4. A hydraulic cylinder 82 is installed on the upper bottom surface of the gantry crane 81. A stamping plate 83 is installed on the lower end face of the drive shaft of the hydraulic cylinder 82. Multiple sets of stamping heads 84 are evenly installed on the lower end face of the stamping plate 83 from left to right. A stamping die 85 is connected to the lower end face of the stamping plate 83 through a stamping spring 86. The multiple sets of stamping heads 84 are slidably connected inside the stamping die 85. The stamping unit 8 also includes a cylinder 87 installed inside the moving groove 4. A moving plate 88 is installed on the telescopic end of the cylinder 87. A stamping column 89 corresponding to the position of the stamping head 84 is evenly installed on the upper end face of the moving plate 88.

[0037] This invention uses a stamping method to form the manifold raw material. Under the combined action of hydraulic cylinder 82 and air cylinder 87, and in cooperation with stamping head 84 and stamping column 89, the manifold raw material on the moving frame 6 is stamped. The stamping method can not only achieve high-speed and large-volume production, but also achieve a high degree of automation and improve production efficiency.

[0038] Specifically, after the multi-stage push rod 5 pushes the movable frame 6, which is fixed with the manifold raw material, to move within the movable slot 4 and transport the manifold raw material to the position of the stamping unit 8, the hydraulic cylinder 82 and the pneumatic cylinder 87 are activated. Under the action of the hydraulic cylinder 82, the stamping plate 83, the stamping head 84, and the stamping die 85 move downward synchronously. The piston rod of the pneumatic cylinder 87 extends upward and drives the movable plate 88 and the stamping column 89 to move upward. The stamping column 89 stops moving when it passes through the corresponding through hole 61 inside the movable frame 6 and contacts the bottom surface of the manifold raw material. The support plate on the stamping column 89 supports and positions the bottom of the moving frame 6 and ensures the stability of the stamping process. When the stamping die 85 descends to contact the upper surface of the placement frame 71, the stamping die 85 stops moving. The stamping plate 83 and the stamping head 84 continue to move downward under the action of the hydraulic cylinder 82. The stamping spring 86 is compressed. The stamping head 84 passes through the lower surface of the stamping die 85 and continues to move downward into the corresponding through hole 61 and cooperates with the stamping column 89 to stamp the busbar raw material on the moving frame 6.

[0039] See Figure 3 The bending unit 9 includes a gantry 91 mounted on the base plate 1 and located on both sides of the moving groove 4. A driving hydraulic cylinder 92 is mounted on the upper bottom surface of the gantry 91. A follower plate 93 is mounted on the lower end face of the driving shaft of the driving hydraulic cylinder 92. Multiple sets of fixed columns 94 are evenly mounted on the lower end face of the follower plate 93 from left to right. A bending assembly 95 is installed between the right side of the multiple sets of fixed columns 94 and the gantry 91. The bending unit 9 also includes a telescopic rod 96 installed inside the moving groove 4. A push plate 97 is mounted on the upper end face of the telescopic rod 96. Locking columns 98, which correspond one-to-one with the positions of the fixed columns 94, are evenly mounted on the upper end face of the push plate 97. The locking columns 98 are elastic telescopic structures. A locking assembly 99 is installed between the locking columns 98 and the upright plate 3.

[0040] This invention uses a bending unit 9 to bend the internal structure of the stamped busbar. A driving hydraulic cylinder 92 moves the bending assembly 95, causing the locking post 98 to extend and move the pushing plate 97 and the corresponding locking post 98 upwards. This allows the upper surface of the locking post 98 to fit against the lower surface of the fixing post 94, clamping the internal gasket structure of the busbar. As the driving hydraulic cylinder 92 moves downwards, the clamped internal gasket structure is pressed downwards and moved to the right under the action of the bending assembly 95, thus achieving the bending process of the internal gasket structure of the busbar. This integrated automated stamping and bending process makes the forming and processing of the PACK battery pack module busbar more efficient and refined.

[0041] See Figure 3 , Figure 6The bending assembly 95 includes a movable rack 951 mounted on the bottom right side of the follower plate 93. A gear 952 is rotatably connected to the front right side of the upright plate 3, and the gear 952 meshes with the movable rack 951. A follower rack 953 meshes with the side of the gear 952 away from the movable rack 951. A top block 954 is mounted on the front side of the movable rack 951. Slider blocks 955 are mounted on both the front and rear sides of the follower rack 953. The sliders 955 are slidably connected inside the sliding plate 957 by a compression spring 956. The sliding plate 957 has a U-shaped structure and a connecting rod 958 is installed on the lower left side. The connecting rod 958 has an elastic telescopic structure. The pushing plate 97 is fixedly connected to the telescopic end of the connecting rod 958. A limiting plate 959 is installed between the upper part of the base plate 1 and the rear of the sliding plate 957. The limiting plate 959 has an L-shaped structure and a clearance groove 950 is opened on the upper part of its horizontal section. The follower rack 953 is slidably connected inside the clearance groove 950 and slidably connected inside the vertical section of the limiting plate 959.

[0042] See Figure 3 , Figure 7 , Figure 9 and Figure 10 A follower rod 971 is installed on the right side of the push plate 97. The follower rod 971 has an L-shaped structure, and a protrusion 972 that cooperates with the top block 954 is installed on the left side of its vertical section. Multiple sets of sliding grooves 931 are opened on the lower surface of the follower plate 93. A sliding block 942 is installed above each of the fixed columns 94. The sliding block 942 is slidably connected in the corresponding sliding groove 931 by a compression spring 943. Position pins 941 are symmetrically installed on both sides of the lower end face of the fixed column 94. Pin grooves 982 are symmetrically opened on both sides of the upper end face of the locking column 98. The position of the pin groove 982 corresponds one-to-one with the position of the position pin 941. A square groove 41 is opened inside the moving groove 4. A moving block 961 is installed on the bottom surface of the telescopic rod 96. The moving block 961 is slidably connected in the square groove 41 by a return spring 962.

[0043] This invention uses a hydraulic cylinder 92 to drive a gear 952, a follower rack 953, and a moving rack 951 to perform bending processing on the internal structure of the stamped busbar. Additionally, a top block 954 and a protrusion 972 work together to move a push plate 97 and a locking post 98 to the right. A fixing post 94, fixed to the locking post 98, moves the clamped internal gasket structure of the busbar to the right, thus achieving the bending and forming process of the internal gasket structure of the busbar. This enables mass production and automation of busbar forming, improving the efficiency of busbar forming in PACK battery pack modules.

[0044] Specifically, after the multi-stage push rod 5 pushes the movable frame 6, which is fixed with the stamped busbar, to move in the movable groove 4 and transports the stamped busbar to the position of the bending unit 9, the rear of the movable frame 6 moves into the groove inside the upright plate 3. The bottom surface of the groove inside the upright plate 3 matches the bottom surface of the support leg behind the movable frame 6, which plays a supporting and fixing role for the movable frame 6. Therefore, during the bending process, the stability during the bending process can be effectively guaranteed.

[0045] Start the drive hydraulic cylinder 92. Driven by the drive hydraulic cylinder 92, the follower plate 93 and the fixed column 94 move downward. The moving rack 951 moves downward synchronously. The gear 952 meshing with it rotates counterclockwise and drives the follower rack 953 to move upward. The slider 955 slides upward inside the sliding plate 957. The compression spring 956 is compressed. At the same time, under the action of the compression spring 956, the sliding plate 957 moves upward with the follower rack 953, driving the push plate 97 and the locking column 98 to move upward. When the sliding plate 957 moves to the upper bottom surface of the limit plate 959, the sliding plate 957 stops moving. The follower rack 953 slides out from inside the relief groove 950. Since the follower rack 953 also slides inside the limit plate 959, the limit plate 959 can limit the movement of the follower rack 953.

[0046] When the locking pin 98 and the fixing pin 94 are located inside the corresponding through hole 61, their opposing surfaces are respectively pressed against the upper and lower surfaces of the internal gasket structure of the busbar, and the position pin 941 moves into the pin groove 982 for positioning. At this time, when the protrusion 972 on the follower rod 971 moves upward and collides with the top block 954 on the front side of the follower rack 953, the follower rod 971 will be displaced to the right, and will drive the push plate 97, locking pin 98, and telescopic rod 96 to move to the right simultaneously. The connecting rod 958 is compressed, and the telescopic rod 96 drives the moving block 961 to move to the right inside the square groove 41, and the return spring 962 is compressed. Positioning and fixing function of pin 941, fixing post 94 moves to the right synchronously with locking post 98. Fixing post 94 drives sliding block 942 to move to the right in corresponding groove 931. Compression spring 943 is compressed. Under the joint action of fixing post 94 and locking post 98, the compressed busbar internal gasket structure is bent to the right, realizing the structural shaping of the gasket structure that contacts and communicates with the battery cell inside the busbar. This makes the gasket located in the middle of the punch hole and on the lower side of its main structure, which facilitates the installation of busbar and battery pack and makes the contact between busbar and battery smooth, making the current output more stable.

[0047] See Figure 4 , Figure 5 and Figure 7The locking assembly 99 includes a support rod 991 installed on the left side below the locking post 98, and a rotating rod 992 connected to the left side of the locking post 98 via a locking spring 993. The rotating rod 992 and the support rod 991 are rotatably connected at the middle via a pin. The rotating rod 992 has an L-shaped structure, and its horizontal section extends to the outer side of the telescopic end of the locking post 98. A groove 981 is provided on the left side of the telescopic end of the locking post 98. When the locking post 98 is compressed, the horizontal section of the rotating rod 992 slides into the groove 981, thereby locking the length of the locking post 98. The locking assembly 99 also includes multiple sets of fixing rods 994 installed on the front end face of the upright plate 3. Each fixing rod 994 has a toggle block 995 installed on the side near the rotating rod 992.

[0048] This invention employs a locking component 99 to lock the position of the telescopic end of the locking post 98. Through the cooperation of the support rod 991, the rotating rod 992, and the locking spring 993, the rotating rod 992 can lock the position of the telescopic end of the locking post 98 when the fixed post 94 and the locking post 98 are in close contact and the internal gasket structure of the busbar is bent. This prevents the telescopic end of the locking post 98 from moving upward and pushing the bent gasket upward when it elastically expands and contracts after bending, thus ensuring the stability of the internal gasket structure of the busbar during bending.

[0049] Specifically, when the push plate 97 moves the locking pin 98 upward under the drive of the hydraulic cylinder 92, the corresponding fixing pin 94 moves downward simultaneously. Their opposing surfaces then press against the upper and lower surfaces of the manifold internal gasket structure. As the fixing pin 94 continues to move downward, the manifold internal gasket structure, clamped by the locking pin 98 and the fixing pin 94, is pressed downward by the movement of the fixing pin 94. The telescopic end of the locking pin 98 is pressed downward by the fixing pin 94. At this time, the horizontal section of the rotating rod 992 slides into the groove 981 of the locking pin 98. Inside, the telescopic end of the locking pin 98 is locked in position. After the bending process is completed, under the drive of the hydraulic cylinder 92, the push plate 97 drives the locking pin 98 to move downward. When the rotating rod 992 on the locking pin 98 moves to the position of the actuating block 995, the bottom end of the rotating rod 992 is pushed to the right by the actuating block 995, the rotating rod 992 rotates counterclockwise, the locking spring 993 is compressed, the horizontal section of the rotating rod 992 is disengaged from the groove 981, the telescopic end of the locking pin 98 is released, and it returns to its original state due to its own elastic telescopic structure.

[0050] After the overall processing is completed, the multi-stage push rod 5 pulls the moving frame 6 back to its original position. Since the busbar material is mostly metal, the stamped busbar can be removed from the placement frame 71 with the help of an electromagnetic hand, suction cup or robotic arm to avoid high temperature burns. Then the busbar raw material is put in and the same operation is repeated.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
